Cisco IOS contains multiple vulnerabilities in the Data-link Switching (DLSw) feature that may 
result in a reload or memory leaks when processing specially crafted UDP or IP Protocol 91 packets.

Cisco has released free software updates that address these vulnerabilities. Workarounds are 
available to mitigate the effects of these vulnerabilities.

This advisory is posted at 

CSCsh04686

Symptoms: With X25 over TCP (XOT) enabled on a router or catalyst switch, malformed traffic sent 
to TCP port 1998 will cause the device to reload. This was first observed in Cisco IOS 
Release 12.2(31)SB2.

Conditions: Must have “x25 routing” enabled on the device.

Workarounds: Use IPSEC or other tunneling mechanisms to protect XOT traffic. Also, apply ACLs 
on affected devices so that traffic is only accepted from trusted tunnel endpoints. 

CSCeh64479

Symptoms: A router reloads unexpectedly when an apparent Layer Two Forwarding (L2F) packet is 
received.

Conditions: This symptom is observed on a Cisco 10000 series that is configured for Virtual Private 
Dialup Network (VPDN). However, the symptom is not platform-specific.

Workaround: There is no workaround.
